TYDZ-500KVA/10KV/0~3KV Contact Type Voltage Regulator

Mode: TYDZ-500KVA/10KV/0~3KV
Single phase            Frequency: 50Hz             Cooling methods: ONAN
Rated Capacity: 500kVA                                    Rated Output Voltage: 0~3kV
Regulating methods: Motor drive                    Rated Output Current: 0~166.6A
Rated Input Voltage: 10kV                                 Aberration Ration of Waveform: ≤3%
Rated Input Current: 50A                                    Starting Voltage ≤1.5%
Short-circuit Impedance:≤7.5%(in range of 50%~100%,impedance is being linearity)
Mode of Regulation: electrical drive
Operation Time: working for 60 min under 100% rated voltage and current
Short-circuit capability: When test transformer discharge to the test object via damping resistance under transient state, short-circuit current reach 2 times of rated value. The discharge last 8 circle will no damage regulator’s winding or mechanical distortion.
Temperature raise: temperature rise of oil surface is less than 55K., winding less than 65K when voltage regulator’s output capacitance reach 360kVA in 10 min.
Product structure: 1.There are upper and lower position limited, oil drain valve, oil level indicator
                                 2.Regulating unit and raise voltage raising units are set together.
Dimension: (L×W×H) 1750×1250×1800mm
Weight <4000kg
